V. Technical parameter
1 . Conductor DC resistance shall meet the stipulation in GB/T3956.
2 . Finished cable shall pass the AC voltage （50Hz、 5min、 3500v） test without breakdown. Water-immersion voltage resistant test is for the single core cable with no armor
3.Insulation resistance
4 . Flame-retardant test
Finished cable shall meet the flame-retardant property test requirement stipulated in IE60332-3 and GB/T18380.3.
5 . Fire-resistance test
Finished cable shall meet the fire resistant test requirements stipulate d in IEC60332-21 and GB/T19216.21.
VI. Feature
Five-core power cable is suitable to use in three-phase five-wire transmission and distribution power system. Separating the neutral wire from the ground wire thus is available for the stable operation of the system and safety of the operator. Moreover, s] nee the five-core power cable is designed in a special tile form, the cable has many features such as a stable structure, lightweight, small outer diameter and so on.
